Phys.org / Climate and competition alone cannot explain Neanderthal extinction, study finds
A new modeling study suggests that greater connectivity between groups may have given Homo sapiens the edge over Neanderthals. Why Neanderthals went extinct and Homo sapiens established a lasting presence in Europe is still ...
Phys.org / A vast Indigenous American genome map exposes lost migrations, ancient ancestry and more than a million new variants
Research into human genomic diversity has a number of applications in biomedicine, evolution, and history. However, many populations have historically been underrepresented on the human genomic map. This is the case of Native ...
Science X / Kakapel rock art traces millennia of painters in Kenya
A recent study published in Azania: Archaeological Research in Africa presents the first millimeter-accurate recording of the paintings at Kakapel rock shelter in Kenya, linking the layers of rock art painted over thousands ...
Phys.org / Nuclear war at Ukraine-Russia border could trigger years of global climate disruption and radioactive fallout
Geopolitical tensions in Eastern Europe underscore the urgency of addressing the climate and radiological consequences of a regional nuclear conflict. Even a small-scale nuclear conflict at the Ukraine–Russia border could ...
Phys.org / Ancient amber reveals a true bug equipped with claws, a highly unusual feature
Amber from the Kachin region of Myanmar has preserved a wealth of fossils, offering insights into the diversity of the Cretaceous fauna of a 100-million-year-old forest ecosystem. The site continues to yield previously unknown ...
Phys.org / This volcano that 'slept' for 100,000 years was never truly quiet
For more than 100,000 years, the Methana volcano in Greece appeared dormant. No lava, no explosions, no ash clouds. It appeared extinct, like many other volcanoes today. An international research team led by ETH Zurich has ...
Phys.org / What if humans could regrow tissue? New study moves science closer
For centuries, the inability to regrow lost body parts has been considered a defining limitation of humans and other mammals. While animals like salamanders can regenerate entire limbs, humans are left with scar tissue. But ...
Phys.org / Milk's hidden carbon bill is bigger than advertised as damaged grass and soils drive emissions higher
Livestock farming causes a significant share of the world's greenhouse gas emissions. According to a new study, the carbon footprint of milk may be considerably larger than commonly calculated when carbon released from the ...
Phys.org / 3I/ATLAS contains 30 times more semi-heavy water than comets in our solar system
New observations of the interstellar comet 3I/ATLAS include the first measurement of the abundance of deuterated water relative to ordinary water in an interstellar object. Astronomers using the Atacama Large Millimeter/submillimeter ...
Phys.org / Scientists discover how the Twelve Apostles were formed—and their real age
Scientists at the University of Melbourne have uncovered for the first time how Australia's iconic Twelve Apostles were formed, finding tectonic plate movements over millions of years lifted and tilted the giant structures ...
Phys.org / Both bonobos and dolphins form unexpected alliances with 'outsiders'
Cooperation is a pillar of human society, promoting an exchange of skills and knowledge between different individuals and social groups. Humans typically do not only cooperate with their own family, friends and members of ...
Tech Xplore / Tiny, knotted robots jump, fly and plant seeds
When a knot lets go, it doesn't just fall apart. It snaps. That simple observation led Penn Engineers to rethink what a knot can do. Instead of treating it as something that holds tension, they asked a different question: ...
